The present work consisted of making use of remote sensing in precision agriculture to publicize vegetation indicators and to detect stress levels of any kind in conventionally grown blueberry cultivation. The use of technology in agriculture in recent years has been applied on a larger scale, remote sensing through a multispectral sensor is one of them that is used to obtain the normalized difference vegetation index (NDVI), to determine the NDVI is made use of the wavelengths that are absorbed and reflected by the leaves of the plant in the red bands (RED) and near-infrared (NIR), by means of the following relationship the values of NDVI = (NIR-RED) / (NIR+RED) are obtained. The capture of these wavelengths was obtained with a camera with multispectral sensors that flew over the surface by a fixedwing drone. The values of this wavelength ratio vary from -1 to 1, with negative values referring to inert objects and values close to unity indicating high vegetation density. The images were processed by a computer, obtaining a mosaic image where areas with low vegetation index were located, the areas with low vigor represents a degree of stress of any kind. It was reviewed in the field and layers of undecomposed organic matter were identified in the root zone, presence of Anomala spp. in the neck and root of the plant. Also by NDVI was calculated the green area index that was a base complement to incorporate other detection systems, which relates the amount of volume of phytosanitary application with the area of foliage. Obtaining less volume of application in areas of less green area and vice versa.
